Cooling Fan Blade - 11521271846

This part is listed by BMW as BMW part number 11521723363 and is described as Engine Fan Blade for E21 323i 81-83, E30 325e/325i 85-87, E12, E28, E9, E24, Bavaria, E23.

This is the fan with 9 blades. Later fans had 11 blades.

The engine fan works at low speeds to pull cooling air through the radiator. It should spin when coolant reaches a certain temperature measured by a sensor on the radiator. If your fan doesn't spin at all or spins slowly, check the temp sensor or the fan clutch.

This part is manufactured by an aftermarket supplier of European auto parts, including many cooling components. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
